Scales the picture to the new size including mask (in case one exists).

This is a self made algorithm which produces nice pictures on all platforms.
It is slower than QuickDraw on Mac OS, but nicer than drawpicture on Windows.
Returns nil on low memory or invalid width and height values.

AntiAlias is set to false if width<=self.width or height<=self.height.

If YieldTicks is 0, no time is given to other threads in your application. If it is a value > 0, this time is waited before a thread switch is done. Setting it to 1 will give away control to another thread after 1/60th of a second. We recommend a value of 3 to 5 for a good reponsibility of your application.

Version 19.4 or newer of our plugin includes scaling for pictures with alpha channel.

Some examples using this method:

• /DynaPDF/PDF with picture direct
